Title: Improvements in or relating to machines for trimming or cutting out workpieces
IPC: C14B5/00
Filed: 1933-05-16
Abstract: 421,177. Trimming boot soles and other workpieces. BRITISH UNITED SHOE MACHINERY CO., Ltd., and JONES, C. T., Belgrave Road, Leicester. May 16, 1933, No. 14136. [Class 31 (i)] Relates to machines for trimming or cutting out workpieces, such as boot or shoe soles, of the kind described in Specifications 23396/06, [Class 31], and 1070/08, [Class 17], wherein a blank is clamped upon a pattern between which and a knife there is relative traversing movement during the operation of the machine in a path determined by the pattern to effect the trimming or cutting out. The machine is designed to avoid danger to the operator from the moving knife or its supporting mechanism when placing blanks into or removing them from the machine, and for this purpose the overhanging portion 1 of the machine frame, on a base portion of which the pattern is supported, extends downwardly and rearwardly directly behind the vertical axis of the rotary table or support 5, as viewed from the front of the machine and substantially at right-angles to the driving shaft. A horizontal work table 9 of substantial size extending on both sides of the portion 1 and above the knife 7 can thus be provided. A triangular portion 11 of the table 9 at the left-hand side is so situated that the hand of the operator reaching thereto is above the path of the knife and its supporting mechanism. A knife guard 51 is arranged in front of the knife edge 7 on a knife clamping member so as to move with the knife. The arrangement and construction according to the invention is described in relation to a machine as described in Specification 1070/08. The machine may be driven throughout its cycle at either of two speeds, or the speed may be varied at any time during its cycle by the operator by a twopart control lever 17, 27 on which the operator must keep his hand throughout the complete cycle of the machine to maintain the power operated mechanism in operation. This same control lever may be used to stop the machine, e.g. in case of emergency, at any period of its cycle. Specification 253,201, [Class 31 (i)], also is referred to.

Inventor: AUSTIN FRANK EUGENE
Filed: 1916-10-05
Abstract: 112,634. Austin, F. E., and Bodde, T. Oct 5, 1916. Gyroscopic apparatus.-In a course-recording apparatus for vehicles, ships, &c. the rotation of the record-surface in azimuth is controlled and effected by gyroscopic ineans. Upon a spider frame S supported on the main frame is mounted aa azimuth stabilizer D, Fig. 4, comprising two gyroscopes geared together, requiring to be set at infrequent intervals by hand after reference to a magnetic compass C. When the vehicle is proceeding in the azimuth for which the apparatus has been set, a contact arm 74 of the stabilizer casing 75 projects between a pair of vertical contact bars 77 upon a disk 16 mounted to rotate loosely on the central spindle 84 of the stabilizer, the casing of which has a supporting-flange 82 resting upon a ball bearing 83 to facilitate relative rotation of the stabilizer and main frame. This will occur when the vehicle changes direction, and the contacts then complete circuit for an electro-motor M adapted to drive a pinion 70 engaging the toothed edge 72 of the disk 16 until the latter is restored into agreement with the constant direction of the stabilizer, whereupon the contacts open.

Title: Improvements in or relating to one-revolution clutch and like devices
IPC: F16D67/04
Filed: 1950-06-06
Abstract: 692,935. Operating clutches. EUMUCO (ENGLAND), Ltd., and EMANUEL, F. June 6, 1951 [June 6, 1950], No. 14143/50. Class 80 (ii). The operating member of a valve controlling a pneumatically actuated clutch and brake has a latch for holding the member in a machinedriving position, a cam actuated by the machine for releasing the latch after a predetermined movement, e.g. one revolution, and a delay valve ensuring brake release prior to clutch engagement. In the embodiment shown in Fig. 1 a clutch 14 driving a forging press is normally held off by springs but may be engaged by pneumatic pressure while a brake 15 normally held on by springs is disengageable by pneumatic pressure. When a solenoid 67 actuating a valve 57 is energised, by closing a manual or pedal switch 37, air is supplied through a pipe 24 to the cylinder of a pneumatically actuated valve 16 which opens allowing air to flow through pipes 33, 19, 25 to disengage the brake. As the operating member 20 of the valve 16 is rocked by the piston 23 against a spring 31 a catch 27, carried by a rod 26 connected to the member 20, passes a sliding latch 28 which holds the valve open. A time-delay device 40, comprising a valve 42 actuated by a, piston 39, is connected by a pipe 38 to the brake operating pipe 25 and functions to connect a pneumatically actuated clutch control valve 30 to the air supply pipe 24. Disengagement of the brake prior to engagement of the clutch is thus ensured. The valve 30 is similar to the valve 16 and connects the clutch to the pipe 33 by way of a pipe 45, an adjustable throttle valve 46 and a bye-pass with a non-return valve 47. The valve 46 retards clutch engagement and the valve 47 allows rapid clutch disengagement. A latch 35 holds the valve 30 in the driving position by engaging a catch 34. The latches 28, 35 are withdrawn at the end of one revolution by cams 11, 12 carried by either the press crankshaft or a countershaft geared thereto. Followers 131 connected by rods 130 and bell cranks 29 to the latches, the withdrawal of which allows the closing of valves 16, 30 by springs 31 and the consequent clutch disengagement and brake engagement. If the operator maintains the switch 37 closed the press will rotate continuously. In a modification, Fig. 2 (not shown), the time delay device 40 is in the form of a throttling valve connecting pipes 24 and 44. In a further embodiment, Fig. 3, a single valve 57, actuated by a solenoid 67 controlled by a switch 68, connects an air supply pipe 51 to a pipe 24 which supplies a brake 15 directly and a clutch 14 via the previously mentioned valves 46, 47. A latch 35 co-operates with a catch 34 connected to the valve operating member 66 and is released by a single cam 12.

Title: Improvements in or relating to spanners
IPC: B25B23/00
Filed: 1943-09-01
Abstract: 569,952. Spanners. BRITISH ERMETO CORPORATION, Ltd., and WILKERSON, R. J. Sept. 1, 1943, No. 14279. [Class 61 (iii)] [Also in Group XXII] - For unscrewing workpieces such as 1 from the headstock 4 of a machine tool, a spanner 12 is pivoted to an arm 8 pivotally supported on a fixed part 7 of the machine. The spanner is held in a raised, inoperative position by a spring 9. When machining of the piece has been completed, the spanner is swung down by hand to engage the hexagon part of the work-piece and the headstock is driven in the reverse direction. As shown, the spanner jaws have a short face 14, a face 15 of full length, and a face 16 longer than and parallel to the face 14, the faces 15 and 16 being joined by a curved face 17 and the face 16 being relieved at its inner end 16a. Owing to this construction, the hexagon part becomes loose in the jaws if the headstock is accidentally started in a direction to tighten the work-piece, and the spanner is withdrawn from the work-piece by the spring 9 when the operative releases his hand. The spanner may have additional jaw faces, or interchangeable jaws, to accommodate work-pieces of various sizes, and the outer corners of the jaws preferably are rounded as at 18.

Title: Planographic dampening apparatus
IPC: B41F7/26
Filed: 1958-05-06
Abstract: 834,175. Lithographic machines. EVANS, O. (Gegenheimer Co. Inc., W.). May 6, 1958, No. 14514/58. Class 100(2) A dampening mechanism for a planographic printing machine comprises a rotatable water-fountain roll for supplying water to the printing surface, a plurality of leaf-spring wiping members having ends of tapered width adjacent to each other, each of the tapered ends being selectively engageable over a variable width with the surface of the roll for removing water therefrom, and means for individually and selectively varying the number of leaf-spring members in engagement with the roll. The fountain roll 20 is of stainless steel and transfers water from the fountain 22 via a messenger roller to a train of damping rollers one of which is axially reciprocated. The leafspring wiping members 30 are made of resilient, transparent or translucent plastic sheet material e.g. cellulose acetate or methyl methacrylate between 0.01.0 and 0.025 inches thick, and are pivotally mounted on a shaft 24 parallel to the roll 20 and carried by brackets 26 fastened to the rear wall 28 of the fountain 22. Each member 30 has a slotted rear end which is gripped between an inturned end 40 of a U-shaped bracket 36 and a plate 48. Fig. 3. which is biased towards the end 40 by a spring 46 surrounding a stud 44 which is slidable in an aperture in the end 40. The spring 46 also biases the head of the stud 44 into contact with the shaft 24 on which the bracket 36 is pivotally mounted, so that the bracket is retained thereby in any position relative to the shaft 24 to which it is turned, the projecting part of the stud 44 being used as a handle when the bracket is moved. The position of each member 30 is thus variable between that in which only the tip 32 of its tapered end engages the roll 20 and in which only a very narrow strip of the roller is wiped free of water, and that in which the whole width of the member engages the roll and a broad strip thereof is wiped. Each member 30 may also be pivoted completely out of engagement with the roll. The underside of the members 30 may be roughened when the latter are made of transparent material so that the lines of contact with the roll are made visible as transparent strips on a translucent ground owing to the contact of the water on the roll 20 with the roughened surface.

Title: Method of and device for plasma-mig-welding
IPC: B23K10/02
Filed: 1972-03-29
Abstract: 1338866 Welding by fusion PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 29 March 1972 [1 April 1971] 14811/72 Heading B3R In joining or deposition of metal by plasma- MIG-welding, wherein an arc is maintained in a gas flow between a non-consumable electrode 9 and a workpiece 35, the arc plasma is constricted by a nozzle 5, a current-carrying consumable welding wire 11 is fed axially of and into said arc plasma, and a MIG-arc is maintained between the wire and the workpiece, the electrode 9 and the wire 11 are connected to positive terminals of two independently controllable current supply sources and the forms of the MIG arc and the material transfer from the wire are varied by varying the current in said wire. The current sources preferably form part of a common control unit. At a low welding wire current there is a drop-like (globular) material transfer which changes gradually as the current is increased into an axial transfer of very small droplets (axial spray). Upon reaching a critical value of welding current (referred to as transition current) there is a change to rotating transfer of very small droplets (rotating spray).  The wire 11 is fed, by controllable motordriven rollers 15, through a guide and contact tube 13 which is connected to the positive terminal of a flat voltage-current characteristic current supply source 33. The electrode 9 (e.g. tungsten) is carried in a holder connected to the positive terminal of a drooping voltage-current characteristic current supply source 29 via an H.F. generator 31. The negative terminals of the sources 29, 33 are connected to the workpiece 35. The tube 13, the electrode holder 8 and a gun body 3 are water cooled through ducts 23<SP>1</SP>, 23<SP>11</SP>, 25<SP>1</SP>, 25<SP>11</SP>, 27<SP>1</SP>, 27<SP>11</SP>. Plasma gas, e.g. argon, and a shielding gas, e.g. a mixture of argon and CO 2  or argon, CO 2  and O 2 , are fed respectively through ducts 19, 21.  As shown in Fig. 3, a low welding wire current produces a MIG-arc in the form of a contracted, non-rotating cylinder within a plasma-arc 37 and provides for a narrow bead with deep penetration. As shown in Fig. 5, at the transition current the MIG-arc suddenly changes into a rotating arc 43 describing a cylindrical surface 45, the end 47 of the welding wire 11 becoming plastic and bent laterally to describe a conical surface 49. This shape of arc is particularly suitable for metal deposition with a wide bead and small penetration. It is found that the transition current increases with increase in welding wire diameter and increase in plasma nozzle aperture diameter, and that deposition rate and arc rotation speed increase with welding wire current increase. The Specification includes examples of butt welds of mild steel plate using 1À6% Mn, 0À8% Si, 0À1% C, balance Fe welding wire: and of butt welding stainless steel plate and deposition of stainless steel on mild steel plate using 20À6% Cr, 9À7% Ni, 1À8% Mn, 0À85% Si, 0À025% C, balance Fe welding wire.
